In the 16th century, before the term mandarin became widespread in the European languages, the word Loutea (with various spelling variations) was often used in Europeans' travel reports to refer to Chinese scholar-officials.
Why do some people get smelly gas after eating eggs? I really love eggs, but I get really bad, sulfurous and rotten egg-smelling gas after eating eggs. This doesn't happen when I eat foods which contain eggs in moderate amounts (cakes, etc), but it does happen when I eat hard-boiled eggs or fried eggs. I don't get any stomach cramps or any other symptoms of allergy, however.
Natural gas exposure can occur when appliances, heating systems and pipes in your home leak gas. Natural gas contains chemicals such as methane, ethane, propane, butane and carbon monoxide. The gas is odorless and colorless, which makes detecting a leak difficult. Therefore, a rotten egg smell has been added to it for easier detection.
